You can leave hull planks thicker and shape in mild bottom contours, but over or undershaping remains a distinct possibility.
A v off the tail is fairly easy to achieve
Flat is easiest to attempt.
The wood is going.to want do do all sorts of different things. My method always tries to form a single concave with most at the rail apex.
A big issue with hws is nose rocker getting flattened out by hull planks pulling and deck planks pushing it down. I glass the multiple stringers to mitigate this tendency.
When I finish making a template in boardcad, how do I create printable hws ribs and stringer templates?
BoardCAD V3.x has its own printable template routines for HWS under the File pulldown. I am not near my PC to say exactly where.
Or save the board as a *.brd file and find an old copy of Jedail's HBTM program for a little more control.
For both programs, the thickness of the wood pieces is an input before running the output.
Be safe, have fun. -J
Thanks alot for the great advice!
You are welcome! Screenshots from said programs below. The HBTM uses an older version of Java that will complain before it runs on Win10.
No matter how many ribs you designed, the board cad print feature, does not use them, but the jdail hws template maker does.
Regarding Bottom Contours:
You can adjust the ribs! Lets say you designed ribs each 15cm. First think, what the bottom contours should be, for example slight concave in the front and double concave vee in the back. Then delete some ribs, but leave the ribs with the maximum contours and the ribs between the sections. For example leave the rib in the middle of the board, because it is supposed to be flat and leave one rib each 30 cm away from front and back. you got only three ribs left. Go to the front rib and pull the most outside construction point on the bottom to -0,5 cm, this designs the front concave! Go to the back rib, take same point and bring it +0,5, resulting in a general vee, then take a point between center and rail and pull it to +1cm. Now you see the bottom blending into a concace between the center and the "vee" point. If you add the ribs in between back again, they automatically blend in the wanted contours. Try this and play around, you soon will realize how it works. To controll everything you just create the 3d model and watch it carefully.
then save and print the plans with the jdail program...
Thanks! Will definitely do that!
Hi guys! I played around on boardcad and came up with a design that I really like... 7'6" midlength board 21" wide 2.5" thick. 45 litres.
Please comment any advice on my design on the pictures below. This board should be a allrounder, for small beach breaks to the occasional hollower point break. I would prefer to use it as a single fin.
Bottom contours going from flat in tip of nose to belly to double concave at wide point to vee at tail.
Please tell me if you cant see the measurements! My pc just wont screeznshot today...
You learned fast! As said, BoardCad is a nice tool and its easy to understand how it works.
Regarding the shape, I think it will work, but I'm more a builder, not a shaper, maybe there are other guys here to give you some input.
I would just recommend one thing. I did more or less the same, I build my first boards using a lot of nice features, but I would give you the advice to start with a very easy shape, meaning bottom all flat. A flat bottom works too and it is much easier to build.
As fast as you tried to understand BoardCad, it shows me, that you will get hooked on board building, so there will be at least some to follow the first board. An in ervery build somthing goes wrong, you need to learn and get experience. I have build more than about 10 woodies now, and in all build there are flaws, fortunately they are smaller and smaller each time and only I do see them, the most people do not. And I still have ideas, which need to be tested, which are potential risks to fail...
So go slow, start easy.
REgarding your build I would ask you to look for wodboardforum.com, but in the moment, the site is down. This would be the place for you to discuss all build features, Sways for me is the place to discuss shapes. Hope that wbf (woodboardforum) will work again soon (See Thread WBF down...)
